^ZAMSTAR: TRIAL OF TUBERCULOSIS REDUCTION STRATEGIES IN ZAMBIA AND SOUTH AFRICA^

The Zambia, South Africa Tuberculosis and AIDS Reduction (ZAMSTAR) trial examined 
two public health interventions that aimed to reduce the burden of tuberculosis by 
facilitating either rapid sputum diagnosis or integrating tubeculosis and HIV 
services within the community.

A total of 24 communities (clusters), 16 from Zambia and 8 from South Africa were
randomly allocated to one of four arms in this 2x2 factorial trial of community
and household interventions.
